In street sweeping apparatus it is a common practice to employ'rotary sweepersand to mount `the same uponv vcars or frames which are propelled along the streets'to be swept, or along thetrack rails of street' car systems, the sweeper' .being suspended un- `derneaththe car or iframe and ordinarily disposed1 in an inclined position.. relative to `theline of travel of the: car or frame.; In

the operation' of sweeping. machines so; construct-ed, the sweepers'are enabled to cove-r a comparatively limited aiea'of streetsurface, `and where such amachine is employed l to clean' away. snow or dirt along :the tracks of. a .st-reet. car system, for instance, the re- .sult is .to leave vthe fsnowor dirt acted upon by. the;sweeperpiled'up in aj ridge or heap lying in a linerparallel to and closelyf adjacent the track rails, frequently making it :difficult and inconvenient orpassengers to board or alight fronirars operating. on the track system, -land for I'pedestrians to cross the street. 'Moreoven if the sweeper is arrangedv to extend. beyondf the. side of the. frame .or car onv which itis mounted,

. whether on lone'side `or thel other, the entire `frame or' carmust be turned around at the :endof the line, or at the terminal of the trip, in .order to enable'the sweeper tol operate on the opposite. side of the track. on the return trip. In manycases it is. inconvenient. audi undesirable to; turn the. .vehicle around.. .Again'fit is frequent-ly the "case -tliatthe presence ofother vehicles yor obtem, thereby necessitating the removal 'of the `nbstruction and the delay of the4 sweeping apparatus iintilf the vehicle or obstruction It is aniongtheA special purposes of our Vpresent invention. to provide a frame or car, which., in onegform of embodiment 'of our invention, we propose to operate on the track rails of a street car system, and to mount thereon a rotary' sweeper in such manner as to permit the sweeper., to be rocked or swung atwill into position -to project or extend beyond eitheriside ,of the carrier',A oryinto position beneath the supporting `frame or car, yas Iexigency may require, and wevproplish such rocking or swinging movements without interfering with the mechanism for rotating the sweeper, and to control AtheV samel inefficient manner, thereby enabling the apparatus to clear away snow, rubbish, trash, dirt or the like from the immediate `vicinity .of the track rails, and on either side of the track rails, the sweeper operating `,be simple and efficient.

on one side of the car or frame while thev latter travels in one direction, and on the other side while-traveling in the. opposite direction, without thel necessityof turning the car or framel around at the end of the line or trip; and to be swung underneath or toward theside of they car or frame in order to pass'by an obstruction in its path.

c While vthe principles involved may be carried outin many specifically different embodiments, ywithout departure from the spirit'or scope .of our invention, as defined in .the claims, lwe will describe one illustrative embodiment which we have found to .In the construction shown, 8 supporting frame, which, in this instance, is in the form of a car, andwhen we refer to a car in this, connection, we wish to include any suitable vehicle or frame. In the form shown the .car 8' is mounted on truck wheels 9 designed to operate on track rails of a street car system, the truck wheels 9 being located at the ends of the car.

Intermediate its ends the body part l() of.

the car` is" elevated or arched, as clearly shown in Fig. 1, leaving the end portions 11, with an open space between them. Connecting'the end portions and forming part of thestructure or framework of the elevated or arched portion 10, is a roof 13, be-

, neath which are channel beams 14, respectively arranged at the sides of the elevated portion 10, and forming longitudinally exl tending tracks. The roof 13, and the track members 14, are supported by a framework including vertical and longitudinally extending beams, braces and struts indicated at 15, 16. y l

Operating in the tracks or ways afforded by the track members 14, are wheels or rollers 17, by and from which is supported -and suspended a carriage 18, which may be shifted back and forth along the track members 14, from end to end of the elevated portion l0 of the car.

Journaled vertically in vthe carriage 18 is a shaft' 19, to which axial rotation may be imparted in any suitable 0r convenient manner. ik simple arrangement is shown wherein a motor 2O, that, when operated,

actuates suitable gearing 21, which rota'- `tively actuates the shaft 19. 'The lower end lof shaft 19, extends belowv the elevated `framework of the car, and mounted there- 'ionto revolve therewith is a frame 22 in which is mounted a horizontally arranged designates a .is shown whereina motor, indicated at 26,

is mounted upon the end of the sweeper `frame 24 nearest the pivot 23, and is carried thereby by suitable' brackets which form journals therefor, as shown, and as will be readily understood..

From this description it will bel seen that byl suitably operating and controllingv the motor 20the vertical shaft 19 may be rotated in either direction and to any desired extent, thereby correspondingly rocking or swinging the sweeper frame 24, into the desired posit-ion to extend from either side of the car, and in any desired angle of inclination relative to the line of travel of the car, or to a position'V underneath the car. In this manner the sweeper is capable of operating over an area of street surface on either side of the track which is limited in distance from the track rails only by .the length of the sweeper itself; It will also be seen that 'a vehicle -or other obstruction in the path of the sweeper when extended from the side of thecar may bev easily passed'by simply swinging the sweeper frame back toward the car to the required extent, or beneath the car, if necessary.

When the car reaches the end of the line or trip thev carriage 18 is simply shifted or l moved in any convenient or suitable manner along the 'track members 14, from one end to the other of the arched or elevated frame portion of the car, and the sweeper then swung out into the proper position on the opposite side of the car, as indicated in full andldotted lines in Fig. 2. In this manner we not only avoid the necessity of turning the car around at the end of the trip or line but we alsol are enabled to posiktion the sweeper in the desired relation and inclination with reference to the line or direction of travel of the car, whether the car travels in one direction or the other.

The motors 20, 26, may be controlled from any suitable or convenient point. However, in order to secure the most advantageous operation 0f the apparatus we propose to control the operation of the motors from a cab 29, which is mounted upon andcarried by the outer or free end of the sweeper` frame 24. A suitable controller, indicated at 30, Fig.,2, locatedin the cab 29' and to which the motor circuits, not shown, are led in .a Well known manner, serves to effect the cab to pass/through the space 12, andbe- -desiredcontrol. In :order to `permit the.`

l`neaththeframe 10,2theupper part 31 of the cab is hinged horizontally tothe lowerlpart thereof, so as to be swungdown out of the k.way .of striking the elevatedframe l of In order to relievethe motor 26 of'undue shock or jar byithe loperation ofthe sweeper 28 lover rough or uneven places, stones or the likein the roadway, said motor may be spring supported, as shown, by means of ahanger 38, passing `through Ea bracket 34,:

f and carrying a collar 35, betweenwhich and the bracket 34, a spring 36 isy interposed.

This secures the desired yielding suspension- Aof the motor.

In operation the sweeper Lis liable to l encounter rough or unevensurfaces, stones,

cobbles, or other small obstructions which -may require a bodily elevation of the sweeper to pass thereover. The pivoting of.4

the sweeper frame 2lon the shaft ort pin 23 permits 'vertical rocking or tilting of the lsweeper and its frame which wille-liable the sweeper yto pass over a large proportion of such obstructions without difficulty; The extension of the frame'Ql to the other side of the axis of pin 23 from theside on which. the sweeper is located, and the yweight of motor 26 which is earriedupon said eXtension affords, to the extent of the weight thereof,a-counterbalancing effect upon the sweeper to facilitate the vertical rocking or tilting movement thereof.

This vertical bodily movement of the sweeper may be facilitated. For example, the-ends of pin 23 may becarried in verti- Y cally elongated slots indicated in dotted lines at 37, Fig. 3. This permits the lentire sweeper frame and sweeper to rise, if re-Y quired or necessary, without' interfering with the tilting action thereof, and atthel sametime' permits the sweeper to rest nor-` mally with the full'-\veiglit thereof and of its frame evenly upon the surface of the street.

The end portions 11 ofthe car may be utilized as cabs for the car operating crew or to carry tools, apparatus or accessories, or for any other desired purpose.

In order to cover the surface of the track rails and intermediate area, auxiliary sweepers 38, of the ordinary arrangement may be employed at the ends of the car, as shown.

Having now set forth the objects and nature of our invention, and a construction embodying the principles thereof, we wish it to be understood that, in its broadest scope as defined in the claims, our invention-.isinot to be limited or restricted tothe details shown and*Y described.

But what we dol claim as new-and Yuseful and ofiour own invention, and desire to secure by Letters Patent is,-
